Abstract

To study the effects of rapeseed residues on weeds growth and the following corn yield, this experiment was conducted in 2009 at Hamedan Agriculture Research Center, Iran. The experiment design was split plot in the form of a randomized complete block design with three replications. Treatments of the experiment were hand weeding (with and without) and rapeseed residues (0, 15 and 30 kg/plot). Results indicated that hand weeding significantly affected all the measured traits of corn, but residue had only significant effect on plant height, ear diameter and 1000 kernels weight. Residue had also significant effect on weeds growth; the highest residue rate (30 kg/plot) was more effective and gave the highest weed control.
